Complications and nutrient deficiencies two years after sleeve gastrectomy

Over a period of 56？months, all consecutive patients who underwent SG were documented in this prospective, single-center, observational study. The study endpoints included complication rates, nutritional deficiencies and percentage of excess weight loss (%EWL).From September 26, 2005 to May 28, 2009, 100 patients (female: male？=？59:41) with a mean age of 43.6？years (range: 22–64) and a preoperative BMI of 52.3？kg/2 (range: 36–77) underwent SG. The mean operative time was 86.4？min (range: 35–275). Major complications were observed in 8.0？% of the patients. During the follow-up period, 25 patients (25.0？%) underwent a second bariatric intervention (22 DS and 3 RYGBP). Out of the total 100 patients, 48？% were supplemented with iron, 33？% with zinc, 34？% with a combination of calcium carbonate and cholecalciferol, 24？% with vitamin D, 42？% with vitamin B12 and 40？% with folic acid. The patients who received only a SG (n？=？75) had %EWL of 53.6, 65.8 and 62.6？% after 6, 12 and 24？months, respectively.SG is a highly effective bariatric intervention for morbidly obese patients. Nutritional deficiencies resulting from the procedure can be detected by routine nutritional screening. Results of the study show that Vitamin B12 supplementation should suggested routinely.Obesity has developed into an epidemic. Approximately 1.7 billion people are overweight, and 312 million are obese [1,2]. In Germany in 2009, 60.1？% of male and 42.9？% of female population was overweight [3]. There are currently no conservative treatments that produce the %EWL results and stable courses observed following bariatric surgery. Obesity is associated with an increased mortality risk [4]. Obesity is also associated with increased health costs. A BMI？=？35？kg/2 is associated with a 200？% increase in health care costs compared the normal weight range [5].As a result of the obesity epidemic bariatric and metabolic surgeries have grown in popularity in recent years, resulting that the number of operations is
